To a solution of 1 (1.26 g, 10 mmol) in acetonitrile (25 ml) was added benzylamine (0.536 g, 5 mmol) and the mixture was stirred. The stirring was continued at room temperature for 4 days. The residue was precipitated by addition of cold water, purified and dried by hexane and under vacuum, to afford 2 as a white solid (1.08 g, 63%).Melting point: 72 °C.IR (KBr, cm–1): 3262 (= C-H aromat); 3080 (CH); 1603 (C=C); 1500, 1472 (C=N); 1507; 1351; 1290; 1230.1H-NMR (400 MHz, CDCl3): δ= 7.4 (s, 5H, Ph); 5.9 (s, 2H, Pyrazol); 5 (s, NCH2N); 3.9 (s, 2H, Ph-CH2-N); 2.3 (s, 6H, CH3); 2.1 (s, 6H, CH3).MS (DCI/NH3, CHCl3) = Calculated for [M]+, C19H25N5= 323.
